Map Scenario 1: Migrating a cell using the command line tools

Before you begin

Supported configurations Supported configurations:

This topic is about configuration migration, such as migrating deployment managers and federated nodes in a network deployment environment. The Application Migration Toolkit for WebSphere Application Server provides support for migrating applications from previous versions of WebSphere Application Server to the latest product version. For information about migrating applications, read more about the Application Migration Toolkit.

Review the migration planning information. See Knowledge Collection: Migration planning for WebSphere® Application Server .

This scenario covers migrating cells on the same host. If you intend to migrate cells to a different host, see Scenario 2: Migrating cell configurations to new host machines using the command-line tool.

About this task

This task describes how to use the command line tools to migrate a cell from a previous version of WebSphere Application Server to Version 8.0. The cell configuration consists of a deployment manager with one or more nodes, a web server, and an application client. All ports are migrated forward into the new configuration. This procedure assumes that the previous configuration is running. For more information, see clientUpgrade command.

Avoid trouble Avoid trouble: Ensure that your setting for the maximum number of open files is 10000 or greater. If the number of open files is too low, this can cause a variety of migration failures.gotcha

Procedure

  1. Run the backupConfig command on the deployment manager and all old nodes
  2. Install WebSphere Application Server Version 8.0
  3. Create the target deployment manager profile
  4. Run the WASPreUpgrade command from the new deployment manager profile bin directory
  5. Verify the console output and the WASPreUpgrade logs for success, warnings, or failure
  6. Run the WASPostUpgrade command from the new deployment manager profile bin directory
  7. Verify the logs for success
  8. Run the backupConfig command on the Version 8.0 deployment manager
  9. Start the Version 8.0 deployment manager
  10. Migrate plug-ins for web servers
  11. Run a migration on application client installations
  12. Migrate nodes
  13. Troubleshooting

Results

You have migrated from a previous version to WebSphere Application Server Version 8.0 using the migration tools.
